Ingredients
Water Phase
- 25.85 g Distilled water | 51.7%
- 1.5 g glycerin | 3%
- 0.15 g Xanthan Gum | 0.3%
- 0.25 g Allantoin | 0.5%
- 10 g 1% of Hyaluronic Acid | 20%
- 0.5 g Colloidal Oats | 1%
Oil Phase
- 3.25 g Avocodo Oil | 6.5%
- 2.75 g Sunflower Oil | 5.5%
- 2.5 g Olivem1000 | 5%
- 1.25 g Cetyl Alcohol | 2.5%
Cool Down Phase
- 0.5 g Calendula Extract (Liquid) | 1%
- 0.5 g Honey Bee Extract (Power) | 1%
- 0.25 g vitamin E | 0.5%
- 0.15 g German Chamomile Essential Oil | 0.3%
- 0.1 g tea tree essential oil | 0.2%
- 0.5 g Preservatives | 1%
PH Modifier (if needed)
- Critic Acid
- Sodium Bicarbonate (baking powder)
Instructions
- Place all oil phase ingredients in a beaker.
- In another beaker, place all water phase ingredients
- Prepare all the cool down phase ingredients into another beaker
- Heat the two beakers in a bain-marie (70-75 ° C).
- Pour the sunflower oil (sensitive oil) before emulsification
- Pour the water phase into the oil phase
- Take the bowls out of the water bath.
- For a small batch like this, use an electric mini whisk to stir continuously for about 5 minutes. If you don’t have a smaller high-speed mixer, you can try making a 100g batch instead of 50g, so you have enough product for your immersion blender like this one to work with
- Cool down ingredients are typically present at very low amounts you’ll need to use an accurate scale—preferably one accurate to 0.01g. Prepare all the cool down phase ingredients into another small beaker
- Allow the cream to cool. When the mix is under 40C, add cool down phase ingredients and mix well after each addition using a flexible silicone spatula
- Check that the pH using a pH strip or pH meter, check that the cream has a pH range that is compatible with your chosen preservative. This range is generally indicated by the supplier of the preservative. If your pH isn’t in a suitable range, you can lower it by adding an acid or raise it by adding sodium hydroxide or sodium bicarbonate.
- Finally, blend in the preservative
- Once the emulsion is cool, transfer the cream into the jar. Allow the emulsion to stand for a while, not closing the jar straight away to avoid humidity building up inside the lid.
Notes
- Because this cream contains water, you MUST include a broad-spectrum preservative to ward off microbial growth. In the event, you notice any change in colour, scent, or texture, chuck it out and make a fresh batch.
- A formula should be written in the percentage of ingredients as well as grams. Our popular formulation calculator can be used to convert from percentages to weight easily. It also gives you a warning alert if any of the category ingredients are out of the recommended range to make sure the ratios between the ingredients are as desired.
- Same for hyaluronic acid, if you don’t have any, replace it with more distilled water
- You can use a different botanical extract in place of the calendula extract/honey bee extract.
- You can always use a different essential oil blend as you wish.
